Overlay a displaced version of the image to create a doubled, ghost-like outline.
When to use it
Silhouettes, gestures and strong graphic edges give the echo something clear to repeat.
How to control it
Adjust Amount, Size and Rotation to control the blend, separation and direction.
A starting approach
Begin with a small separation. Watch faces and lettering, where doubled edges become noticeable quickly.
Combine with intention
Choose one main direction first. Compare with the effect reduced or off before adding another treatment. Check the exported photograph as well as the preview.
